Description
Technical field
The invention belongs to new crop varieties to cultivate field, the specially a kind of breeding method and implantation methods of drought resisting rice.
Background technique
Rice is important one of the cereal crops of the mankind, and cultivation and edible history are all quite long.The current whole world has one
Half population eats rice, mainly in Asia, south of europe and tropical America and parts of Africa.The total output of rice accounts for world's grain
Food crop yield third position is lower than corn and wheat, but can maintain the life of more population, so 2004 are set to by the United Nations
" International Year Of Rice ".
But domestic rice is mainly rice, the multidigit agricultural sciences including academician of the Chinese Academy of Sciences Hong Mengmin, Zhang Qifa
Family points out that drought and water shortage has become the key restraining factors of rice in China yield safety guarantee.Related statistics shows, in
State's agricultural water accounts for the 70% of total water consumption, but agricultural irrigation water use efficiency is only every cubic metre of 0.8 kilogram of production grain, not as good as hair
Up to the 40% of country.This high cost with low efficiency results in the deterioration of the excessive exploitation and ecological environment to water and soil resources.China is per capita
Occupy a quarter that water resources quantity only has world occupancy volume per person, belongs to water resource fragility state.And space division when water resources in china
Cloth is extremely uneven, area between, rainfall very different between season.Especially after mid-July, the trend of rainwater reduction is most
Obviously, just locating the mature Critical growing period of the staple crops such as rice grouting this when, the demand to water is maximum, crops
Yield is unable to get guarantee.
In order to guarantee that the country to rice class demand, has become inexorable trend to the research of upland rice, main reason is that: (1)
Rice dry-farming can make full use of natural precipitation, so that the plantation of rice is no longer influenced by the limitation of manual priming, so as to expand energetically
Monitoring of Paddy Rice Plant Area improves rice yield, while can save a large amount of agricultural water, reduces production cost, increases economic efficiency；
(2) be conducive to low-lying land, water sand, the transformation of river bank, intermountain water outlet ground, such plot plantation paddy field lacks irrigation item
Part, plantation dry land summer is easily flooded, and long-term grain yield is extremely low, and being changed to rice dry-farming grain yield can be doubled and redoubled, economy effect
Benefit biggish can improve.But existing dryland rice is not able to satisfy domestic demand the problem is that low output.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of breeding methods of drought resisting rice, realize paddy in water sand
Ground and river bank etc. are planted on the higher soil of sand content, and the cultivated area for both having improved paddy in turn ensures institute's rice cultivation
Yield.
To realize the above-mentioned technical purpose, the specific technical solution that the present invention takes is a kind of breeding method of drought resisting rice,
Include the following steps: A, seed selection, selects the highest rice of yield as No.1 seed in existing rice；It selects in existing dryland rice
The optimal dryland rice of drought resistance is as second seed；B, seed is handled, by No.1 seed using being exposed to the sun, sterilize, impregnate and vernalization
It is spare after processing；By second seed using spare after being exposed to the sun, sterilize and impregnating；C, soil is cultivated in selection, and No.1 seed is selected
Rice soil selects mixed soil as soil is cultivated as soil, second seed is cultivated, and the mixed soil includes following weight
Each substance of part: pass through 3-10 parts of the farmyard manure of disinfection, by 5-8 parts decomposed of stalk powder, compound fertilizer 1-3 parts, rice soil
5-15 parts, 10-15 parts of pond sludge and 15-18 parts of silt particle；D, the placement for cultivating soil, is put into one for the cultivation soil of No.1 seed
In number cultivation dish, No.1 cultivation dish wide 8-15cm, deep 20-25cm；The cultivation soil of second seed is put into No. two cultivation dishes, and two
Number cultivation dish wide 8-15cm, deep 40-50cm；No.1 cultivation dish is staggeredly placed with No. two cultivation dishes；E, it sows, it will treated one
Number seed is seeded in No.1 cultivation dish, and second seed is seeded in No. two cultivation dishes, wherein the depth of planting 5-8cm of No.1 seed,
The depth of planting 15-20cm of second seed；F, it harvests for the first time, collects all mature paddy；G, first seed selection, by first
The paddy of secondary harvest carries out disinfection, impregnate and vernalization after sowed, the soil for sowing selection is composite soil；The composite earth
Earth includes each substance of following parts by weight: 3-10 parts of farmyard manure by disinfection, by 5-8 parts decomposed of stalk powder, compound
1-3 parts fertile, 21-30 parts of rice soil and 10-15 parts of pond sludge, further include silt particle, and the parts by weight of silt particle are rice soil parts by weight
3/2；Depth of planting is 15-20cm；H, secondary seed selection selects the spike of rice that yield is high during choosing is chosen seeds for the first time, takes paddy and sow,
The soil that sowing is selected includes each substance of following parts by weight: passing through 3-10 parts of the farmyard manure of disinfection, by decomposed straw powder
5-8 parts last, compound fertilizer 1-3 parts, 20-30 parts of rice soil and 10-15 parts of pond sludge, further include silt particle, and the parts by weight of silt particle are water
4 times of rice soil parts by weight；Depth of planting is 15-20cm；I, step H is repeated 3-5 times, obtained paddy is drought resisting rice.
Technical solution as an improvement of the present invention, No.1 seed after planting, carried out respectively in germination period and heading stage
It irrigates.
Technical solution as an improvement of the present invention waters to soil after planting during secondary seed selection, watering
Amount guarantees wet soil.
Another object of the present invention is to provide a kind of implantation methods of drought resisting rice, include the following steps: to select sand soil
Earth is laid with mixing organic fertilizer in soil surface, is exposed to the sun, sows, turn over and water；Wherein, the mixing organic fertilizer packet

Technical solution as an improvement of the present invention, the depth of deep ploughing are 20-30cm.
Technical solution as an improvement of the present invention, the depth turned over are 15-20cm.
Beneficial effect
Interlaced arrangement is carried out using rice and dryland rice then to sow, and realizes the purpose that rice and dryland rice are mutually pollinated, so that
Sow obtained part paddy while the characteristic with drought resisting and high yield for the first time, but this characteristic and unstable；Therefore, it is necessary to again
Secondary screening.
During screening again, the water-retaining property of soil is controlled by control sowing the content of soil, so that not drought-enduring
Seed cannot germinate or germinate after cannot grow vigorously, realize to paddy carry out drought resistance screening.By manually choosing
The mode of high yield spike of rice is selected, realizes the screening to rice yield.The two is implemented in combination with the sieve of high yield and drought resistance to paddy
Choosing.
Compared with prior art, it has the advantage that are as follows: do not need to carry out artificial pollination to paddy, when reducing artificial work
Between；By adjusting planting soil, when repeat sowing screens paddy seeds, gives paddy a kind of winning bad naughty phase buffer, guarantee
The quality and yield of paddy when screening paddy seeds.
